Help on creating DAX formula

[Anonymous]

Hello everyone
I am a sort of a beginner in DAX so I can't figure out how to get the result I want. I have the model shown below

What I want to do is this:
1) Filter Snapshot Info to get the latest [Date Time]

2) Get [Value] of Time Profile where [Snapshot ID] = 'Snapshot Info'[Snapshot ID] && [Start Time Interval] = 'Snapshot Info'[Start Time] from the previous step

Nood question I know but I'm stuck

Thank you!

Please try this measure expression.  The relationship is already making sure the IDs match, but adding the TREATAS() can pass the value of Start Time to the Start Time Interval column too (if they match exactly).

Value Measure =
CALCULATE (
    MAX ( 'Time Profile'[Value] ),
    TREATAS (
        VALUES ( 'Snapshot Info'[Start Time] ),
        'Time Profile'[Start Time Interval]
    )
)

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Regards,

Pat

Hi @mahoneypat 
It almost works. One thing left to do is get the latest Snapshot ID which I get by getting the latest 'Snapshot Info'[Date Time]. The measure is taking into account all Snapshots for now.

My bad.  Misread your post.  Please see if this one works.  If not, please explain more on how you are using this measure.

Value Measure =
VAR __latestdate =
    MAX ( 'Snapshot Info' )
RETURN
    CALCULATE (
        MAX ( 'Time Profile'[Value] ),
        'Time Profile'[Start Time Interval] = __latestdate
    )

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Do you want that as a measure or as a calculated column?
